LooPER WITH sLIDING CUTTER 7 Sheets-Sheet 7 ATTORNEYS United StatesPatent Qiihce 3,070,983 Patented Jan. l, 1953 York Fiied Mar. 19, 1958,Ser. No. 722,561 7 Claims. (Cl. i6-84) This invention relates to ahooking attachment which incorporates a cutting device.

Hooks are used in the textile industry for many things. The loopers tobe described herein are related to hooks in that they can perform afunction in knitting, weaving, tufting and sewing to create a pile inthe fabric produced. Loopers of the type described herein may not, atfirst sight, appear to be a novelty in this art, because loopers arecommoniy used in the various fields of textile manufacturing. However,loopers perform one function and one function only: to make loops in afabric and hold such loops until thery are bound in properly in theinterlacing threads of the fabric.

The loopers of this invention differ considerably from those formerlyknown. They lend themselves not only to making loops, but also tocutting those loops in intervals or continuously, as the case may be.The simplicity of the device leands itself to becoming a part ofpractically any cloth manufacturing unit known heretofore, such aslooms, knitting machines, tufting machines, sewing machines, and thelike. Naturally, for each of the mentioned machines to which the deviceof this invention may be attached, the mechanical combination whichoperates the device will have to be adapted to fit into the mechanicalcombinations which the particular machine offers.

Therefore, it is a primary object of this invention to provide a loopand cutting device combination that makes it possible for machines whichmanufacture flat goods to manufacture also pile fabrics of a cut anduncut pile.

It is another object of this invention to provide a looping attachmentfor looms, said looping attachment to be used in lieu of wires on a pilefabric loom, and said looping attachment being adjustable in such a waythat it may either make loop or cut pile or both on the surface of thefabric produced by the loom.

Another object of the invention is to provide a pile forming attachmentfor flat bed knitting machines, or a sinker attachment for circularknitting machines, wherein formers of the type of this invention areused, which pile formers lend themselves to incorporating in knittedfabrics pile forming units that will help to manufacture a fabric havingpile that is cut or uncut, or both.

A still further object of the invention resides in the provision of alooping and cutting attachment for a tufting machine which differs fromdevices of a similar sort of tufting machine in that the pile which isbeing cut is cut in the center rather than on the side. Therefore, atufting machine thus equipped performs as well as a wire would performon a loom.

This invention has a further object the provision for adaptation tosewing machines in order that loops or cut pile may be formed by theattachment of this invention in conjunction with the sewing machine, towhich such units of our invention are adapted.

This invention also lends itself to non-woven fabrics where threads arepulled away from insertion areas and where such threads, after beingadhered to a given area, are left in loop form or cut form, as may bedesired.

These are just some of the objectives of the present invention. In orderto facilitate the understanding of it there has been shown in theaccompanying' drawings the preferred form of this invention as it isused in combination with a knitting machine, wherein:

FIGURE 9 is a horizontal sectional view taken on line 9-9 of FIGURE 8.

As previously stated, the principles of this invention may be applied tonumerous manufacturing devices for cloth, and by the incorporation ofwhich a pile fabric forming operation is provided. Since the usage ofthis device is so varied, other similar combinations will occur to thoseskilled in this art. The reason that such additional combinations arenot presented is the fact that anyone acquainted with the art of textilemanufacture, and especially one acquainted with the art of manufacturingpile fabrics, could readily adapt the principles of the disclosedinvention to the particular type of machinery to which it is to beattached. A showing of one preferred from of the invention, this being acombination of the basic parts of a flat bed knitting machine with thepertinent related parts of this invention is, therefore, deemedsuiiicient. It is unnecessary to show the whole knitting machine,because it is substantially the same type of knitting machine that isgenerally used in the art.

Referring to FIGURE 1, the warp mechanism of the knitting machinecomprises a plurality of knitting needles 111 reciprocated in needle bed140 by a cam 141 carried on and rotated by drive shaft 142 operated byconventional means. The cam 141 is shown in phantom and on the sideopposite that from which the view is taken has circular groove in whichthe follower 145 rides to provide positive movement in both directions.Follower 145v is mounted on yoke slide bar 14d which is suitably securedto the needle driver 143. The yoke slide bar 144i slides back and forthon slide block 155 carried on rotating drive shaft I142. It should benoted that the needle bed 141B is mounted on cross beam 16). The needlesare pulled backwardly by the return pull unit 156 secured to the needledriver 143 by cap screws 151 and 152, A downwardly extending front part161 of the return pull unit is held in position by cap screw 153. Thisfront part 161 engages the needle butt 112 on needle 111.

In this particular example it is important that the cloth which cornesoff the knitting machine be under substantial tension. This isaccomplished by leading the cloth over polished idler roller 184i ontotake-up rollery Spaced forwardly from the needle bed 149 are a pluralityof warp yarn guides 100, one for each needle, clipped onto guide bar191. The bar 191 is secured to a plurality of brackets 1&2, one end ofeach bracket having a collar 163 ixedly mounted on shaft 104. Warp yarn266 is threaded through the eye 110 of each warp yarn guide lili).

Referring particularly to FlGURES 5, 6, and 7, the looper and cutterattachment comprises a plurality of slotted hooks 1, each having anintegral hook spring clamp portion 2 which secures the hook to holdingbar 2i). This holding bar has a plurality of spaced parallel slots onone face and a longitudinally disposed groove in the opposite face toreceive and retain the spring clamp portion of each hook. The holdingbar 2d is carried by one end of rectangular bracket 35 having sides 35amounting bearing blocks 42 at their ends. These blocks 42 are pivotallymounted on shaft 43 carried in shaft bearings 43a extending from thebase 36a.

Base 36a has a pair of side portions 36 which carry cutter holding bar21. This holding bar has a plurality of spaced parallel slots in oneface and a single longitudinally extending groove on the opposite facefor holding a plurality of cutter blade holders lll is alignment withslotted hooks 1.

The cutter blade holder 10 has an integral spring clamp portion 11 whichis snapped onto the cutter holding bar 21 in the same manner as thelooping hook 1. The cutter blade 12 is snapped onto the blade holder 10,as will be described later.

The base 36a has a transverse slot 22 in which an operating lever 47 isslidably mounted by slide assembly 45. The lever 47 is pivotally carriedon shaft 43 and has a cam follower plate 52 on its free end. Actuationof the lever 47 causes it to rotate about shaft t3 to swing the cutterholding bar in an arc. The extent of such movement is limited by stopblocks 53 mounted on sides 35a of bracket 35.

As indicated in the various figures of the drawings, the slots in thehook holding bar 20 and the cutter holding bar 21 are aligned with eachother in order that each cutter blade 12 may slide back 'and forth inits respective and aligned slot of hook 1.

The looper and cutter attachment is mounted on the knitting machine inthe following manner. ri`he sides 35a of bracket 35 are secured on fronthooking shaft 3ft by means of a collar lil affixed to said shaft, thussupporting the entire attachment thereon. Bracket 41 is pivotallymounted on second front hooking shaft 31 as well as on front hookingshaft 30 and has an integral projecting pile height adjustment lever 4dwith a slot 43 therein. Connecting rod 81 has an end portion Sil whichrides in slot t8 while its other end is connected to a slide bar S2mounting a cam follower 83 which engages cam 84 secured on front driveshaft 75. Rotation of said shaft 75 causes cam 84 to verticallyreciprocate slide 82, thus producing rotation of bracket 41 about shaft31. Bracket 41 is also secured to shaft 30, said shaft together with allparts mounted thereon will pivot about shaft 31. Since the hooking andcutting attachment is iixedly mounted on shaft 30, the entire attachmentwill therefore pivot about shaft 31. By varying the stroke of rod 81,the amount of rotation about shaft 31 will be changed and obviouslyresult in a varying height of the loops formed by the looping hooks 1which are caused to move up and down by this movement.

The above-described mechanism serves only to produce an up and downmotion in the looping hooks, the back and forth movement of the hooksabout shaft 3d being accomplished in the following manner. Referring toFIGURE l, a connecting arm 97 is mounted on and secured to shaft 3i) anda rod 85 is fastened to the free end of the arm 97. This rod extendsrearwardly over and beyond the needle board 140 where its end lug 95 isslidably received in slot 96 of lever 93 pivotally mounted on bearingshaft 99. Cam follower 94 on lever 93 engages cam 86 on drive shaft 142to pivot lever 93 yabout shaft 99 and thus impart a reciprocating motionto rod 85, thereby rotating shaft 3i) through arm 97. Rotation of shaft30 causes the looper and cutter attachment mounted thereon to oscillatethereabout and thus produce a back and forth motion of the looper hooks1.

Since the ,front hooking shaft 3l? is caused to reciprocate in agenerally vertical manner by rotation about shaft 31 and, further, sincethe back and forth movement of the looper hooks is produced by rotationof shaft 3ft, it follows that combined adjustment of the two rnechanismswhich produce these motions is necessary in order to achieve properlooping hook motion.

As previously mentioned, the looping hooks 1 and the cutter bladeholders `10 are mounted in aligned slots in the hook holding bar and thecutter blade holder bar, respectively. Thus, by proper adjustment theblade 12 is slidably positioned in slot 5 of each looping hook 1. Asshown in FIGURE 5, the hook 1 has an integral spring clamp 2 and a hookportion 3 having a slot 5 therein.

As illustrated in FIGURES 8 and 9, the blade holder 1l) has a slot 13 inits forward end with a downturned lug 15 extending downwardly and overthe open end of the slot. The slot is so formed that a thin spring-likeelement 14 is left to aid in holding the blade in position. Thegenerally triangular blade 12 has a centrally apertured portion 17`conforming in shape to the cross-section of lug 15. The blade 12 isslipped into the slot '13 so that the apertured portion 17 of the bladewill lit over the lug 15 to hold said blade in position. The blade has acutting edge 16 extending directly outward from the end of the holder.

The cutting action whereby the cutting blade 12 is reciprocated in theslot of its respective looping hook to cut the pile loop held thereby isaccomplished as follows. Cutter holding bar 21 is carried by sideportions 36 extending from base 36a to which is-secured a lever 47pivotally mounted on shaft 43. The end of lever 47 mounts a cam followerplate S2 engaged by roller 51 carried on the end of cam lever Silpivotally mounted on shaft 39 by means of collar 54. Rod end portion 70of rod '71 is connected to lever 5t? while the other endV of the rod isfastened to slide 72 carrying cam follower 73 engaging cam 74 secured onrotating shafts 75. Cam '74 causes slide 73 to reciprocate and throughrod 71 and lever 5@ rotates lever 47 about shaft 43. Thus base 36arotates about shaft t3 and through holder 10, cutter holder bar 21 andside portions 36 connected to the base 36a produces an oscillatingmotion of cutter blade 12 in the slotted portion of the looping hook 1.

A spring 1d extending between cutter holder bar 21 and the bracket 35which is fastened to the looping hook bar 2t) acts to return the bar 21to its lower position when the blade is not in cutting position.

It will be realized that what has been described represents only oneembodiment of the invention, and that there are other ways of mountingthe looping hooks 1 and the blade holders 1li onto the looping andcutting units. One way is to weld these parts onto regular stock, andanother is to make a die that molds all these parts as a unit in oneoperation. The reason for showing the particular embodiment of FGURES 6and 7 is that it has been found that fine parts like the loopers andblade holders are subject to rapid wear at excessive speeds and maybreak at different times. Hence, 4the snap-on type of the looping hookand the blade holder, respectively, make it easier to replace eachindividual part without much diiculty or shutdown time.

As seen in FGURES 6 and 7, the looper hook holding bar 20 and the cutterholding bar 21 are made in sections of a given length. This has a veryimportant purpose. As indicated in FIGURE 1, there is an additional rod62 whose end 61 is connected to lever 60 piv- 3 otally mounted on shaft33 by collar 64. This mechanism would be a duplicate of that previouslydescribed for operating the cutter blades l2, yet operated by adifferent shaft, namely, 38 in somewhat different time sequence andattached to a separate looping hook and cutting unit so as to vary thecutting timing and thus vary the load on the machine.

There may `be incorporated in the utilization of this invention a looperwith a sliding cutter having more than one cutting mechanism-Thisadditional cutting mechanism facilitates the manufacture of manydifferent ,fabrics. Should the looper and sliding cutter unit attachedto cam lever 50, wherein the sliding cutter is operated by the mechanismof cam 74, be operated vin the same manner as cam lever 60, all the pilemanufactured in the fabric will be cut at the same time. Should the camlever 5d, however, be operated by a cam that is not identical with theone shown in cam 74, the sliding cutting unit and blade holders loperated by cam lever 6@ will cut the pile of the fabric at intervalsdifferent than those Operated by cam lever Sti. From this explanation,it will be readily understood that there are a great many variations inthe types of fabrics that can be manufactured in accordance with 4theprinciples of the disclosed invention.

In looms of great width, such as are used in the manufacture ofbroadloom oor coverings, the width of each individual attachment withits sliding cutter determines the variations in fabric that may bemanufactured. The width of such attachments may vary from that of thecombination of a single looper with a single sliding cutter, such asshown in FIGURE 5, to a group of such units as shown in FIGURES 6 and 7.Some of the looping hooks 1 may be clamped onto the loop hook holdingbar 20 without a blade holder clamp lli. Others, in turn, may have thecombination of the looping hook 1 with the blade holder it). All thesemay be varied again by having some looping hooks 1 grabbing yarn, otherlooping hooks 1 not grabbing yarn; and some blade holders 10 being incutting position within the looping hooks i, and others being in suchposition but not operated.

The mounting and operative relations of the pile looping, holding, andcutting means of this invention are most clearly shown in FiGURES to 9,inclusive. Considering first the enlarged and semental views of FIG-URES 5, 8, and 9, one upright looping hook l is shown to have a loopinghook clamp 2 at its lower end part ,a pile holding hook portion 3 at itsupper end, and a length- Wise aperture 5 extending rearwardly anddownwardly of its upper end to receive and guide a cutting blade l2 inits pile cutting movement. A loop hook holding bar 2d is detachablyengaged with the lower end of the yielding clamp formation 2 and has alongitudinal groove l for more positive retention. The extended bladeholder member l16 has a resilient clamp formation 11 on one end forinsertion in one of the uppermost channels of the cutter holding block21, and retention of its end in groove 24 extending lengthwise on theunderside of said block.

The replaceable cutter blades l2, which are a special feature of thisinvention, are generally triangular in shape and have the liexibility ofan ordinary thin safety razor blade. There is an unsymmetrical andsloped cutting edge 16 at the base of the triangle and a rectangularnotch at its truncated apex (FIGURE 8).

The adjacent end part of the rod-like blade holder 10 is formed with anoutwardly directed slot or socket 13 at one side, which provides anintegral leaf spring 14. In opposition to spring 14 there is a stiff lugl5 with an inturned end interlocking with a complemental transverse slot17 in the blade outwardly of the socket i3.

The cutting attachment which has been described is an outstandingfeature because of the utility and economy it aifords. A worn ordefective blade can be replaced in an instant by deilecting it againstthe leaf spring part 14 d to release it from the lug 15. A new blade 12can be snapped in instantly past spring part 14 and into two-wayinterlocking engagement with slot 17 and the rectangular notch at theapex of blade l2.

The following examples are representative of the fabrics that can beproduced by use of the novel principles of this invention:

Example l The apparatus disclosed herein is operated in such manner thatthe loopers and sliding cutters work each time a pile row is formed.This operation will manufacture a pile fabric with all cut pile.

Example 2 The apparatus is so operated that all the loopers operate ineach pile row, but only part of the sliding cutters operate in one pilerow; and part of the sliding cutters operate in each alternate pile row.Such operation will make a fabric that has part loop and part cut pile,alternately.

Example 3 The apparatus is so operated that only some loopers havesliding cutters and other loopers are without sliding cutters. Thisarrangement will manufacture a fabric which has lengthwise rows of cutpile and also lengthwise rows of loop pile.

Example 4 The novel attachment provided by this invention is caused tooperate in such a manner that some of the loopers are working and otherloopers are idle, and some of the loopers that are in operation havesliding cutters, and other of the loopers that are not in operation donot have sliding cutters, thereby providing means for manufacturing afabric which may have in each pile row raised pile yarn and non-raisedpile yarn, and in which some of the raised pile yarn is cut and some ofthe raised pile yarn is uncut.

Example 5 The attachment is similar to the one described in Example 4,but has some of the hooks non-operative in one pile row and operative inanother, and vice versa, and some of the pile hooks that have slidingcutters operate in one pile row and not in the successive pile row,thereby making possible a design with symmetric features.

Example 6 The attachment is the same as the one particularized inExample 5, but the cams for the loopers and sliding cutters have chainsthereon, which, in given pile rows keep the various parts operative ornon-operative, respectively, in repeats that are predetermined in thedesign of a fabric. This combination will make possible production of atri-dimensional fabric with a dat background and raised pile, whereinthe raised pile is cut or uncut, as the design requires. The primaryadvantage of this modification is that no jacquard mechanism or similarknown mechanisms for designing is necessary in order to vary the featurewhich imparts versatility to the attachment of this invention.

FIGURES 5 through 9 afford a very clear understanding of the basicfeatures of the invention, namely, a single looper 1 and a blade 12sliding therein. The looper or looping hook l is attached to the springlooping hook clamp 2 mounted on the holding bar Ztl and titting into thehorizontal groove 4 of said holding bar. The sliding cutter 12, operatedas previously explained, consists of a blade holder member it) extendinginto the adjacent end portion of the blade holder clamp 11. The cutterholding bar 21 has a plurality of transverse grooves 24 receiving theclamps il of the blade holder member itl. Towards the spliced orlongitudinally slit looping hook i the blade holder iti extends into aninturned lug l5 over which a complemental aperture formed in blade-i2parallel to its cutting edge engages. The blade now operates up and downin the aperture of the spliced looping hook 1. As mentioned previously,the spliced looping hook 1 and the blade holder do not necessarily haveto be snapped onto the bars but may be attached thereto by other means.Again, this is shown as one of the preferred Aforms of the invention.Cutting unit stop blocks 53, which are shown in FEGURES 1 and 7, arevery important to prevent the sharp edge 16 of blade 12 from hitting thepile holding hook 3 at its uppermost point which could thereby bedulled.

While a preferred embodiment and certain modifications of the presentinvention have been illustrated and described herein, it is not intendedto limit the invention to such exemplary disclosures, but such changesand modifications may be made therein as come within the scope of thefollowing claims.
